[usual Anon but posting from the parental wifi - they switched it on for me!]
We did discuss upthread whether all the HI sightings were genuine, and those who had seen the tweets thought some were attention-seeking fakes from teenagers who wanted followers.
Some sightings are doubtless also mistaken identity, though the recent Twitter guy seems to be an Avengers/Chris Evans fan. I'd have thought he would be less likely to get it wrong. I'm less sure what I think about a tumblr anon who says Brie mentioned she had lunch with TH because she was "correcting" a wrong Twitter sighting!
However in my view the jury's out till we get a sighting in Australia!
Hope everyone had a good holiday! I need looser trousers...
